Resumo(s): | The effective integration of 2D materials such as monolayer transition metal dichalcogenides (TMDs) into photonic waveguides and integrated circuits is being intensely pursued due to these materials’ strong exciton-based optical response. This work presents a platform where a 2D heterostructure (WS2-hBN) is directly integrated into the photonic mode-center of a novel polymer ridge waveguide. Finite-difference time-domain simulations and collection of photoluminescence from the guided mode indicate that this system exhibits significantly improved waveguide-emitter coupling and mode confinement over a previous elastomer platform. This is facilitated by the platform’s enhanced refractive-index contrast and a new method for mode-center integration of the coupled TMD. The integration is based on a simple dry-transfer process that is applicable to other 2D materials, and the platform’s elastomeric nature is a natural fit to explore strain-tunable hybrid-photonic devices. The demonstrated ability of coupling photoluminescence to a polymer waveguide opens up new possibilities for hybrid-photonic systems in a variety of contexts. |
